Stochastic Model of Multiple Cracking Process in Fiber Reinforced Cementitious Composites
نویسنده
چکیده
An analytical model that allows prediction or reproduction of the overall stress-strain relationship of a high performance cementitious composite in tension is presented. Through consideration of stochastic character of the composite microstructure, the model captures the sequence of crack formation and the load fluctuations that are characteristic for the process of multiple cracking. The proposed model is used to reproduce/predict hardening stress-strain curves of an Engineered Cementitious Composite (ECC). Results capture the effect of introducing artificial flaws on the composite ductility, which has been reported in experimental studies.

Flexural Behavior of Cementitious Composites Reinforced by Synthetic Fibers
The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...

متن کاملMicrostructure variability and macroscopic composite properties of high performance fiber reinforced cementitious composites
High performance fiber reinforced cementitious composites have made major advances in recent years, to the point where they are being adopted in building and bridge constructions. The most significant advantage of HPFRCC over conventional concrete is their high tensile ductility. However, the tensile strain capacity has been observed to vary, most likely as a result of the variability of the mi...
